I had to do the same thing, juise, when I reopened three years ago. The roof leaked so the whole thing smelled musty and the seats were literally sixty years old and falling apart. The curtains were moldy and all of the carpeting reeked. I had to gut the whole thing and start over fresh. It wasn't fun but it really made the difference and let people know that we were very different from the folks that used to own this place. Good luck.

Believe it or not, the most important rooms to keep smelling fresh and clean are your restrooms. A dirty toilet will turn customers away every time. (It's a given that the booth and its equipment must be spotless.)
